Sourdough Trail: Brainard Lake to Camp Dick - 13.3 Miles Round-Trip

The Sourdough Trail stretches 12.5 miles from Rainbow Lakes Road to Camp Dick in the Roosevelt National Forest. This versatile trail runs S-N along the eastern edge of the Indian Peaks Wilderness Area on grades ideal for hiking, running, skiing and snowshoeing.

There are several access points along the way; the following describes the Sourdough Trail's northern half between Brainard Lake Road (s) and its terminus at Camp Dick (n). The Sourdough Trail is accessed from the new trailhead facility just outside the Brainard Lake Recreation fee station:

Note that some older map depictions of this junction are not to scale. Downhill grades moderate to the first of two Wapiti Trail access points, a winter use-only trail.

The Sourdough bends NE to a large meadow and pond with good views of Niwot Ridge and several iconic summits of the Indian Peaks Wilderness (2.0 miles : 9,712'). This boggy, aspen-ringed area is a good place to find wildlife. A steep grade resumes through lodgepole to a break with views of St Vrain Mountain and the Beaver Reservoir basin ( 2. 5 miles : 9,566').

A mild descent continues past the second Wapiti Trail split (2.9 miles : 9,456'), and uneventfully to a large clearing at CR 113 and the Beaver Bog Trailhead (3.85 miles : 9,195').

Note the contrast between the thick pine forest to the south, and sparsley treed hillside to the north. This area was taken by fire some years ago, but is recovering well as flowers, grasses and aspen have sprouted in replenished soils and newly opened space.

Head north from the Beaver Bog Trailhead into the burn-recovery area. The trail rises through sparse pine and young aspen to a crest with good views of St Vrain Mountain (12,162').

It levels across a dirt road (4.2 miles : 9,310') and drops to the Beaver Reservoir Trailhead on County Road 96 (4.9 miles : 9,176'). Follow trail marker #835 across the road and keep north.

The Sourdough Trail moderates to a long footbridge (5.35 miles : 9,122') and enters a notably tall and diverse swath of forest (5.5 miles). It reaches a split for Coney Flats Road (6.1 miles : 8,928'), and begins a mod-steep descent to a split for Buchannan Pass Trail and Camp Dick (6.5 miles : 8,698').

Follows signs for Camp Dick, where the trail ends near Campsite #35 (6.65 miles : 8,672').

Worth Noting

The Sourdough Trail is variously referred to as Trail #835 on many maps and signs.

This is a muti-use trail that sees moderate use all times of year. Honor yield protocols for horses and skiers.

Though grades are moderate and trail conditions are good, there is significant climbing and distance on the return to Brainard Lake. Plan travel time and resources accordingly.

Moose are sometimes seen along the Sourdough Trail, especially in the fall during the rut. Moose can be aggressive during this time, and possess deceptive speed. Maintain a safe and respectful distance.
